SPECIFICATION forming part of Letters Patent No. 551,302, dated December10, 1895. Application filed July 11, 1894. Serial No. 517,2 t8. (Nmodel.)

To all whom, it may concern.-

Beit known that we, JOHN \V. BROWN and ALBERT GEHRT, of Quincy, in thecounty of Adams and State of Illinois, have invented a certain new anduseful Improvement in Baling-Presses, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming part of this specification.

Our invention relates to certain improvements in presses for baling hay,straw, excelsior, and the like; and our invention consists in featuresof novelty hereinafter fully described and pointed out in the claims.

Figure I is a detail top view showing the power end of the press withpart of the sweep and sweep-head. Fig. II is a similar view, the sweepand sweep-head being omitted. Fig. III is an end view of the power endof the press, showing part of the sweep. Fig. IV is avertical sectiontaken on line IV IV, Fig. I. Fig. V is a detail top view showing thejoint of the pitman and showing also the upper guiden'oller of thepitman. Fig. VI is a detail side view of the parts shown in Fig. V. Fig.VII is a detail side elevation showing the baling portion of the press.Fig. VIII is a top view of the part shown in Fig. VII. Fig. IX is adetail vertical section of the baling part of the press, the feedermechanism and the plunger-gear being shown in elevation. Fig. X is adetail top view of the condenser. Fig. XI is detail view showing amodification of the connection between the pitmanrack and theplunger-toothed segment. Fig. XII is a detail side elevation showingamodification in connection with the baling portion of the press. Fig.XIII is a side elevation of the power end of the baling-press inconnection with the plunger-gear mechanism.

Referring to the drawings, 1 represents the baling-chamber of the press.

2 represents the plunger; 3, the pitman, which is jointed at 5represents a timber or sill extending rearwardly from thebaling-chamber, and on the outer end of which the power mechanism issupported. The inner end of the timber 5 is supported on pins 6,1ittedin a strip or timber 7, secured to the baling-chamber 1.

8 represents a roller journaled in a casting 9 secured to the inner endof the timber 5, the roller forming a support for the inner end of thepitman (See FigsVII, IX, and XIII.) The inner end of the pitman isformed with a rack 10, engaging a toothed segment 11, mounted on ahorizontal shaft 12. The toothed segment 11 is provided with a crank orarm 13, having a slot 14.

15 represents alink connected at its outer end by means of a pin to thecrank-arm 13, the pin 16 fitting in the slot 14. The inner end of thelink is pivoted at 17 to the plunger 2.

Instead of engaging directly with the toothed segment 11, the rack 10may do so, through the interposition of a pinion 18, as shown in Fig.XI. 7

19 represents a cam formed upon or secured to the toothed segment 11, orif desired this cam may be rigidly secured to the shaft 12, whichcarries the toothed segment. The object of this cam is to force theconnection 16, between the link 15 and the crank 13, to the outer end ofthe slot 14 as the rack 10 moves forward, and thus the plunger 2 isretracted with but a short movement or throw of the toothed segment 11.It will be understood that in. the absence of the cam 19 the point ofconnection between the link 15 and the crank 13 would remain (exceptwhere there might be a severe return of the plunger under the expansiveforce of the pressed material) at the inner end of the slot 14; butby-providing the cam 19, which comes against the link 15 as the toothedsegment moves from the position shown] in Fig. VII to the position shownin Fig. IX, the point of connection between the link 15 and the crank 13is moved to the outer end of the slot 1i, and thus the plunger is drawnback with a movement of the toothed segment 11 comparatively short towhat would be necessary in the absence of the cam 19. Near the joint :l:the pitman is supported by a roller 20, journaled in a casting orbracket 21, secured to the timber 5. (See Figs. VI and XIII.) Above thepitman is a roller 22, journaled in the bracket 21, (see Figs.V,VI, andXIL) and which serves to prevent upward movement or strain of thepitman. The outer end of the pitman is connectedat 23 to a crank 21,secured to or form ed integral with a pinion 25. The pinion is connectedto the frame 5, preferably as shown in Fig. IV, by means of an extension26 thereon, journaled in a bushing 27, fitted in the timber. Theprojection. is held in the bushing by means of a bolt 28, passingthrough the pinion, through the projection, and through a washer 2f)fitting against the lower end of the bushing 27. The journal of thepinion 25 is eccentrically located with relation to the pinion, as shownin Figs. 1, II, and IV.

30 represents a triangular cog-wheel, or cogwheel having three equalsides, the teeth of the cog-wheel meshing with the teeth of the pinion25. The eccentric journaling of the pinion 25 will miss the constantmeshing of the teeth of the cog-wheel with the teeth of the pinion,notwithstanding the distance from the center of the cog-wheel to thecorners of the triangle is greater than the distance from the center ofthe cog-wheel to the sides of the triangle. The cog-wheel has a hub 3.1,fitting a stud secured to the timber 5. The cog wheel is looselysupported on this journalstud, so as to turn freely. Over the hub 31 isa sweep-head 33, to which the sweep 34 is connected. The head is held inplace by a bolt 35 passing through the sweep-head and through the stud32, as shown in Fig. IV. Ve prefer to rabbet the upper end of the hub 31into the lower surface of the sweep-head, as shown at 36. The sweep-headis carried independently of the cog'wheel 30, except when theprojections 37 on the sweep-head come against projections 38 on thecog-wheel, and then the cog-wheel is caused to turn with the sweep-head,and as it is turned its motion is transmitted to the plunger 2, throughmeans of the pinion 25, the crank 24, the pitman 3, the rack 10, thetoothed segment ll, the crank 13, and the link 15.

As the corners of the triangular cog-wheel pass the pinion 25, theplunger is free to rebound without its movement or force being impartedto the sweep, as at such times the lugs or projections 37 on thecog-wheel will simply leave the lugs or projections on the sweep, and asthe sweep continues to move, the lugs or projections thereon comeagainst the lugs orprojections on the cog-wheel again and the plunger isagain advanced.

The cog-wheel 30 and the pinion 25 being mounted on separate centers,and the parts being so disposed that the corners of the cogwheel engagewith the pinion as the crank 24 and pitman 3 assume a parallel position,great power is obtained at the time that it is most neededthat is, whenthe final pressure is being made by the plunger upon the material beingbaled. By making the cog-wheel 30 in triangular form there are threeforward movements of the plunger at each revolution of the cog-wheel orat each revolution of the sweep, thus making a press which is capable ofbaling alarge amount of materialin a given time.

It will. be understood that the number of cogs in the pinion 25 isone-third of the number of cogs in the wheel 30, so that at eachrevolution of the wheel 30 the pinion turns three times around, thusgiving three forward movements to the plunger at each revolution of thesweep. The result is a press capable of baling a large amount ofmaterial within a given time.

40 represents a feeder-blade, pivoted at 41 to a lever 42, the leverbeing pivoted at 43 to a standard or standards 44 mounted on themachine. The lever is of approximately bellcrank form ,the upper armcarrying the feederblade and the lower arm being preferably curved belowthe pivot 43 and having a pin 45, (upon which may be afriction-roller,)fitting in a grooved arm 45, secured to the plunger.The feeder-blade has an extension 46 above the pivot 41, and to thisextension is pivoted one end of a link 47, the other end of which isconnected to the standard 44 or to a projection 48 on the standard. Thislink is for the purpose of imparting a parallel movement to thefeeder-blade, so that as the feeder-blade enters the mouth of the pressit will move in substantially a vertical direction instead of on the arcof a circle, as it would do were it rigidly connected to the end of thelever 42. The upper arm of the lever 42 is pivoted to the lower arm at49, and back of the pivot 49 the upper arm is connected to the lower armby means of a spring-bolt 50. By thus connecting the two arms of thelever together the feeder-board can yield slightly under severe strain,(as, for instance, in case of an overcharge of material for the press,)and thus danger of breakage is avoided.

Assuming the parts to be in the position shown in Fig. VII, with theplunger forward, the feeder will be in its raised position. As theplunger recedes, and before it reaches the limit of its rearwardmovement, the bend 51 in the arm 45 comes against the pin 45 in thelower arm of the bell-crank lever 42, which causes the feeder to beforced from the position shown in Fig. VII to the position shown in Fig.IX. Before the feeder descends, a charge of the material has been throwninto the condenser, and is forced by the feeder into the baling-chamber.As the plunger moves forward again, carrying the arm 45 with it, thefeeder is raised by the pin 45 moving upward in the groove of the arm45, and it will be observed that both the downward and upward movementof the feeder is very quick, making it possible to press three chargesat each revolution of the sweep, and also have the feeder in the properposition as much of the time as it is possible "for it to be in thisposition.

52 represents the fixed sides of the condenser, and 53 the movable andflexible sides. The sides 53 are hinged to a back piece 54, from whichextends strips or arms 55, along the top sills of the press. Thesestrips or arms are provided with projections 56, (which may be armedwith friction-rollers,) fitting in slots 57, formed in the upper end oflevers 58, pivoted or hinged at 59 to the lower part of thepress-chamber, the levers being located on the outside of the press andhaving angular slots 60, which receive pins (31 carried by the plunger,the pins, if preferred, being provided with friction-rollers where theyfit in the slots 60. The pins move in slots 02 in the sides of thepress, when the sides are closed. Otherwise no slots 62 are needed. Wehave shown the plunger provided with extensions 63 for carrying the pins61. As the plunger recedes, the levers 58 will be moved from theposition shown in full lines, Fig. VII, to the position shown in dottedlines, and as they are thus moved they will draw the movable part of thecondenser forward toward the fixed part, and condense the materialjustprior to the descent of the feeder. The slots 57 are made toaccommodate the vibratory movement of the lever 58 to the horizontalmovement of the projections 56, for, as will be seen, when the arms orlevers 58, as shown in both forward and backward stroke, Fig. VII, theprojections 56 will always be near the top of slots 57; but when thelevers stand in a perpendicular position the projections 56 will belower down in the slot 57.

The slots 60 aremade angular. The lower parts of slots 60 are made forthe purpose of accommodating the pins (31 in their horizontalmovement-that is to say, the pins 61 move in the lower part of the slots(30 as the levers pass over their pivot-lines.

The upper parts of the slots 60 are for the purpose of making anintermittent movement to the condenser-head 5i. Vhen the plunger isforced toward. the toothed segment 11, the arms 58 being hinged at 59and moved by the pins 61, the projections 56 move in a horizontalposition much faster than 61, owing to its greater distance from thecenter 59. Then just before the plunger reaches its backward stroke thepins 61 will move into the upper parts of slots 60. Hence the arms 58will cease to move. Then the condenser-head 54 will,by means of theprojections 56, be at rest for the time being until the plunger startson its forward stroke,when pins 61 will move out of the upper parts ofslots 60 to the lower parts of slots 60. Then the arm 58 will movetoward the baling-chamber and carry with it the projections 56 and thecondenser-head. From this it will be seen that the condenser-head 54:has an intermittent movement, allowing it to condense, the materialbeing fed very fast un-. til the condenser-head 54:11815 reached the endof the feed-hole. Then it rests until the feeder 40 has forced thematerial into the press and resumes its position shown in Fig. VIII.

Other means (see Fig-XII) might be used to move the condenser with thearm 58. For instance, one end of a link 56 could be attached to the rearof projections 56. The other end could be attached to the upper end ofarm 58. By referring to Fig. VII it will be seen that this simply leavesoff the slot 57 and connects the projections 56 to the arm 58 by thelink. Of course the connection of the link to the projections 56 couldbe made farther back toward the press and by this means make a longerlink, the link only being used to overcome the up-and-down motion of thevibrating arm 58, as it moves backward and forward.

7 0 represents the division-block holder, and

71 one of the blocks. This holder is mounted on top of the press and iscapable of having a slight forward movement to allow the blocks to fallby gravity into the press. The holder consists of a base 7 3, which isheld to the press by means of suitable slides 7i that allow it to moveslightly, and a vertical. part 74;, into which the blocks are insertedsidewise, the lower ends of the blocks resting, when the holder is inits rear or normal position, upon the top of the press. The top of theblocks are held by a flange or lip 74 on the head. 75 represents a leverpivoted at 76 to the press-hopper, and connected by a link 7 7 to theblock-holder. At the proper time the blockholder is moved slightlyforward, through means of the lever 75, until the block is over thefeed-opening, or until the block passes the corner A, Fig. IX, of thefeed-opening. The block will then fall, by gravity, into the press, andthe holder is then moved back to its normal position. Should the blockbe obstructed, or not fall entirely into the press by gravity, it willbe struck by a plate or proj ection 78, secured to the feeder-plate 40,and will thus be moved by a positive pressure until it is entirelywithin the baling-chamber. By thus making the bloclcholder, andarranging it in a vertical position, a very simple means of insertingthe division-blocks without taking hold of them with the hand is provided.

80 represents a fixed cam or plate, secured to the press in front of thetoothed segment 11 on the side to which the crank 13 moves. The pin 16that connects the link 15 to the crank moves behind this plate when theplunger is making the last part of its forward movement and the firstpart of its rearward movement, the result being that the pin 16 will beheld to the inner end of the slot l-l: during the first part of thebackward movement of the mechanism, so that the plunger will be carriedback by the crank-arm, and the pin 16 not allowed to move in the slot 14before the crank has reached a position at, or substantially at, rightangles to the length of the press, and then at about this time the cam19 comes against the link 15 and forces the pin 16 to the outer end ofthe slot in crank-arm.
